===================== What is Port Scanner? ===================== Port Scanner is a tool that allows you to scan a group of IP addresses looking for the presence of specific incoming TCP/IP ports. This is a large benefit to anyone managing a TCP/IP network, or to anyone who is concerned with the possible security risks that some TCP/IP tools present to their network. Using an intuitive interface that allows you to specify the start and end addresses of a scan, you can quickly check a specific machine, a subnet, or an entire domain. Port Scanner comes predefined to scan for the most common TCP/IP services, and provides a quick way to add new ports to any scan. In addition, Port Scanner lets you scan a subset of the existing ports, and to save subsets into named groups for easy recall. Scan results can be easily printed or save to a file. Port Scanner requires a WinSock compatible TCP/IP stack, and is fully Windows 95 compatible. ================= How Does it Work? ================= Port Scanner begins at the location you specify as the Start Address and traverses every valid IP number until it reaches the location you specify as the End Address. At every step in the scan, Port Scanner attempts to open a connection to each port you have selected in the Port List. If a successful connection is made, Port Scanner records that information in the results file. How Do I Obtain a Copy? Port Scanner is available as shareware from Blue Globe Software.
